Fedi based system at a combined cycle power plant in USA

This case study reports on the application of fractional electrodeionization (FEDI) in the production of high purity deionized water. The advantages of this two-stage dual voltage technology over conventional electrodeionization (EDI) are discussed, including better quality of treated water, ability to handle feed water fluctuations, optimized power consumption, and quick on-site regeneration of media. Opening data and experience from one power plant is presented.
